Hi, I’m Soumen

Software Engineer (Java, Spring Boot, AWS)

I build production-grade backends and microservices: Java, Spring Boot, event-driven systems on AWS, and measurable reliability. I also run self-hosted infrastructure in the Trails lab.

About me

A short introduction
About Soumen

Software engineer with over seven years of experience in Java and Spring Boot, shipping APIs, data-heavy services, and distributed systems in product teams. I work across the stack with REST and event-driven design (Kafka); databases such as PostgreSQL, Oracle, MySQL, and DynamoDB; and cloud and delivery on AWS with Docker, Kubernetes, and CI/CD. I care about clear design, safe releases, and how systems behave in production. Outside of work, I run self-hosted infra (Nextcloud, Money Trails, Soil Trails, NAS, etc.) in the Trails Labs ecosystem.

Highlights

Recognition, outcomes, and how I work with teams

Excellence — Claude Code, skills, faster delivery

Intuit

Recognized for excellence by a Senior Staff Software Engineer and a Senior Manager for championing adoption of Claude Code and for building a comprehensive set of reusable Claude skills. That helped us land the work in about 1 week versus a 4-week estimate—without trading away review depth or quality.

Full-time offer after long-term contract

Intuit

Started on the client side through a vendor as a contractor. After a 2-year engagement, Intuit extended a full-time offer based on delivery quality and how I worked with the team in production.

Contractor to FTE in 5 months

Oracle Cerner

Joined in a contract capacity with Oracle Cerner. Strong execution in the role led to a full-time offer within 5 months, continuing with the same client and product area.

“Coach of the Quarter” — team award

Oracle Cerner

Received this business-unit award for a strong quarter, including clear ownership in resolving a production incident and keeping stakeholders aligned on impact and next steps. I also led training and knowledge-transfer (KT) for new joiners and supported them in ramping up on the stack, processes, and how we deliver.
